Application filed July 13, 1906. Serial No. 325,999.

To all whom it may concern:

Be it known that I, HERMANN SANDvoss, a subject of the German Emperor, residing at Neuss-on-the-'Rhine, Germany, have invented new and usefullm rovernents in Regulators for Liquids, &c., of which the following is a specification.

This invention relates to a regulator for liquids on exhaust outlets, etc., in which mercury or a similar material, when. influenced by the heat, actuates a piston or plug to open or close a valve.

In the accompanying drawing: Figure 1 is a longitudinal section of my improved regulator, showing the valve open, and Fig. 2 a similar section of the upper part thereof, showing the valve closed.

An outer casing c, is provided with a liquid, steam or air inlet a, at one end, and an outlet b, near the other end. Within casing 0, is inclosed a tube (1, of such a diameter that an annular passage k, is formed between casing c, and tube d. This tube is received at its lower end within a socketed screw plug 0, that closes the bottom of casing 0. At its upper end there is mountedon tube d, an annular cap h, having a dependflange h, surrounding the upper end of Cap h, has an inner screw thread.

the tube. which is engaged by a threaded perforated plug h the oWer reduced end of which proects through cap h, into tube (1, as at 7?. A stem 0, plays wlthin upper part of tube d, and passes through plug M, by which it is guided. The u per end of stem e, carries a valve Z, adapte to close against a seat 1%, controlling inlet (0. Valve stem e, is nor mally drawn down by a surrounding spring f,

abutting at the top against pr'o ection h andvalve Z, is raised against its seat m. In this way the flow of liquid is stopped until the temperature of the regulator again falls, when valve Z, will be opened by spring I claim: I

A device of the character described, comprising a casing having an inlet and outlet, an inclosed mercury tube, an annular threaded cap fitted thereon, a perforated screw plug engaging said cap, an inlet valve having a spring-influenced stem that passes through the perforated screw plug into the mercury tube, a head at the bottom of the stem, and a flexible casing secured to said head and to the screw plug, substantially as specified.
